Sesamoids are small bones that are only connected to tendons or surrounded in muscle. This only appears in a few places in the body, one of which is the foot. Two very tiny sesamoids are found in the underside of the foot near the big toe. One is on the outer side of the foot and the other bone is close to the middle of the foot. This structure provides a smooth surface for the tendons to slide over, which helps the tendons move muscles. They help with weight bearing and also help to elevate the bones of the big toe. So now that you know what sesamoids are, you might be wondering what sesamoiditis is and what its symptoms are.

Sesamoiditis

Just like any other bone, sesamoids can unfortunately fracture. The tendons surrounding the sesamoids may also become irritated or inflamed and this is what sesamoiditis is. Sesamoiditis is also a form of tendonitis and is a common condition among ballerinas, runners, and baseball catchers due to the pressure that is constantly placed on their feet.

Symptoms of Sesamoiditis

Symptoms of Sesamoiditis may include:

Pain under the big toe or ball of the foot

Swelling and/or bruising

Difficulty in bending and straightening the big toe

Treating Sesamoiditis

Treatments include:

Resting and stopping any activity that could be causing pain and inflammation

Anti-inflammatories, such as ibuprofen and aspirin only after consulting your physician

Icing the sole of the foot

Wearing soft-soled and low-heeled shoes

Cushioning inserts in the shoes

If symptoms persist after treatments, you may need to wear a removable brace for 4-6 weeks to help the bones heal. Call your podiatrist today to ask any questions about sesamoiditis and get on your way to pain-free feet once again!
